Decode the story of Elizebeth Friedman, the cryptologist who took down gangsters and Nazi spies In this picture book biography, young readers will learn all about Elizebeth Friedman (1892–1980), a brilliant American code breaker who smashed Nazi spy rings, took down gangsters, and created the CIA's first cryptology unit. Her story came to light when her secret papers were finally declassified in 2015. From thwarting notorious rumrunners with only paper and pencil to “counter-spying into the minds and activities of” Nazis, Elizebeth held a pivotal role in the early days of US cryptology. No code was too challenging for her to crack, and Elizebeth’s work undoubtedly saved thousands of lives. Extensive back matter includes explanations of codes and ciphers, further information on cryptology, a bibliography, a timeline of Elizebeth’s life, plus secret messages for young readers to decode.

"Along with a brief explanation of the workings of cipers and cryptanalysts, the computer program that accompanies this book provides a replacement for paper and pencil, which has always been a burdensome requirement in operating on ciphers. I think the tedium of a manual trial and error approach might tend to discourage a newcomer to the world of codes and ciphers. These computer programs take over that task and eliminate the tedium." -From foreword

This book reveals the historical context and the evolution of the technically complex Allied Signals Intelligence (Sigint) activity against Japan from 1920 to 1945. It traces the all-important genesis and development of the cryptanalytic techniques used to break the main Japanese Navy code (JN-25) and the Japanese Army’s Water Transport Code during WWII.

The First Enigma Codebreaker

The First Enigma Codebreaker

Autor: Robert Gawlowski

Número de Páginas: 210

The First Enigma Codebreaker is the story of a man who started a revolution in cryptology and the conflict between man and machine. This is a powerful story of the life of Marian Rejewski and how history can affect individual lives, presented to the public for the first time. This examination of how Marian Rejewski changed the course of cryptology is of great interest to everyone from the avid historian to Hollywood film producers and all those in-between. As Gawlowski’s biography shows, Rejewski was an unassuming man who used his mathematical, skills as well as his extensive linguistic abilities, to start cracking the Enigma code before passing the baton on to the now renowned Alan Turing. This is a fascinating, human story about the man Marian Rejewski, which also ties up the loose threads of the Enigma story and shows the importance of the Polish involvement in that process. The First Enigma Codebreaker looks at those involved in cracking the Enigma and also takes a look at an aspect that has rarely been discussed in great detail, the story of Marian Rejewski himself, and how he endured life in post-war Communist Poland shining a light on situations such as how Rejewski...

Code-Breaker and Mathematician Alan Turing

Autor: Heather E. Schwartz

Número de Páginas: 35

Have you ever wished that you could do something heroic to help your country? When Alan Turing was a boy, he was fascinated by math and science. Later, Turing's math skills would help Great Britain win World War II. Turing's parents and teachers thought he'd be better off dropping math in favor of more gentlemanly studies, such as literature and Latin. But he stuck with it, and by the start of World War II in 1939, he was ready to take on the biggest challenge his country faced: Nazi Germany. Turing put his advanced knowledge of math to work decoding secret German messages. His ideas not only helped Great Britain turn the tide of the war—they provided the foundation upon which much of modern computing and artificial intelligence is based.
